I have a 6800 and have gotten it to sync (and even flashed). I dont remember the whole process, but to start you out, go to your device manager and look at the USB section, there should be a PPC listed. (if not, i'm not sure what you do, lol). Click on its properties to find out which usb port the phone is in, and if you have synce installed, type
synce-serial-config ttyUSBx (x being the usb port number)
then
synce-serial-start

you'll probably have to sudo it, but i dont remember what i did after that (ended up making a windows partition so i just use that for PPC stuff only pretty much).

If you have any questions, shoot me a PM...Oh, and sorry for beating a dead horse.
